These argumetns have been questioned in 8th comment of Bug 9350:

Obsoletation isn't enough. Parser support for <wbr> should be delegated to
quirks-mode. Thus, this bug has been renamed to: "Delagate <wbr> support to
quirks-mode - make it have zero effect in no-quirks and almost-standards".

JUSTIFICATION for delagating it to quirks-mode: 

* <wbr> is conceptually very unclear and misunderstood. There is no unique
usecase.
* no single browser implements it in sane way - they all differ
   See: http://www.w3.org/Bugs/Public/show_bug.cgi?id=9711#c2
* IE has already delagated support to Quirks-Mode only.
* Making <wbr> have zero effect in standards mode is pretty risk free: Due to
the fact that no browser really implements <wbr> in full,  the text levels
effects (that is: the effects on searching, selection, doubleclicking,
clipboard copying) are in some cases zero and in other cases close to zero. 

For more arguments, see my comments in the bugs that I have made this bug
dependent on.
